How Our SQL Query Sandbox Works

Our SQL Query Sandbox provides a safe environment to learn and test SQL queries using mock data.

Available Tables:

  • users - id, name, email, age, city, active, created_at
  • orders - id, user_id, product_id, total, status, order_date
  • products - id, name, category, price, stock, rating
  • employees - id, name, department, salary, hire_date, performance

Supported SQL Features:

  • SELECT - Select specific columns or all columns (*)
  • WHERE - Filter results with conditions
  • ORDER BY - Sort results (ASC/DESC)
  • LIMIT - Limit number of results
  • LIKE - Pattern matching
  • AND/OR - Combine conditions
  • Comparison operators - =, !=, >, <, >=, <=

SQL Query FAQ

Only SELECT queries are allowed for safety. All destructive operations (INSERT, UPDATE, DELETE, DROP) are blocked.

Yes! You can perform INNER JOIN operations between tables. Example: SELECT u.name, o.total FROM users u INNER JOIN orders o ON u.id = o.user_id

No! All data is stored locally in your browser's memory. Nothing is sent to any server. You can reset to original data anytime.

Example Queries

Basic SELECT

SELECT * FROM users

Filter with WHERE

SELECT * FROM users WHERE age > 30

Pattern Matching

SELECT * FROM users WHERE name LIKE 'J%'

Sorting

SELECT * FROM products ORDER BY price DESC

Limit Results

SELECT * FROM orders LIMIT 5

Join Tables

SELECT u.name, o.total FROM users u INNER JOIN orders o ON u.id = o.user_id
